PAM

Hey everyone! I had some freetime last night and I noticed that I have several RFID cards and and RFID reader and I almost do nothing with them. After thinking a little bit about what I can do with RFID reader, I came up with an idea! NFC RFID Linux PAM (Pluggable Authentication Module)! So next time for logging into my computer, user should have an RFID card, otherwise, even entering correct username+password combination, will not work.
